RAIL ANCHOR.

Application filed January My invention relates to rail anchors and has for its principal object the provision of a one-piece anchor device of novel and improved construction which may be Vmade of relatively light stock without sacrificing the strength required in devicesl of this character to resist the creeping movement of railroad rails.

A more Vspecific object is to provide an imio proved one-piece resilient anchor which is so formed as to be tensioned during its application to a rail to effect astrong spring grip on opposite edges of the rail base and which will be further tensioned when the device is pressed against a cross tie bythe longitudinal creeping movement ofthe rail.

The invention has for` a further object, the provision of a rail anchor device having the improved arrangement and construction of parts hereinafter described and claimed for carrying out the above stated objects, and such other objects as'will appear from the following description of the embodiment shown in the drawing.

In the drawing:

Fig. 1 is plan view of a railroad rail, showing a rail anchor device constructed in accordance with my invention applied thereto.

Fig. 2 is a side elevation of the anchor device shown in Fig. 1 showing'the anchor in its applied position on the base flange of a railand showing in dotted lines a position assumed by the anchor during its application to the rail,and

Fig. 3 is a view in perspective of the anchor device shown in Figs. 1 and 2.

The embodiment of my invention shown in the drawing, consists of a yolre 1() which extends across the rail beneath the base 11 thereof, and engages the opposite edges of said base. The yoke is made, preferably, from a single piece of resilient metal bent at the middle, as indicated by the reference numeral 12, to provide two arms 13 and 14. The upper edges of the arms, intermediate their ends, are recessed to provideshoulders 15, 15'L1 at one side of the rail and shoulders 16, 16a at the other side. The shoulders 15, 15a are notched to provide vertical edges 17, 17a adapted to bear against the vertical edge 18 of one base flange of the rail, and to provide small jaws'19, 19a which fit over the upper corners of the said base ange. The upper portions of the jaws 19, 19a are in- Cin 15,-1926. Serial No. 1,406.

clined upwardly, so as to provide cam surfaces 19. The bend 12 is formed preferably with a radius of such length that the jaws 19, 19 are normally spaced apart and so that the arms'may converge toward the opposite edge of the rail base. The angle of converg ence of said arms is preferably such that they normally engage each other adjacent the shoulders 16, lthe latter being spaced a short distance away from the edge 20 of the rail base. The'end portions 21, 22, of the arms are bent in opposite directions so as to be substantially parallel to the adjacent edge of the rail base when the anchor is applied to the rail. The extremities of the edge portions 21, 22 are bent inwardly and are recessed to provide jaws 23, 23a and 24, 24a adapted to grip, with rm wedging engage ment, the upper and' lower surfaces of the rail base. what longer than the upper jaws, so as to provide a relatively large surface for engagement with the cross tie or other sta tionary part of the road-bed. The distance from the vertical edge 17, 17a to a horizontal line drawn through the vertical surfaces 25, as represented by S in Fig. 3, is normally less than the width of the rail base, whereby the end portions 21, 22, are ieXed inwardly toward the adjacent edge of the rail base when the jaws 19, 19t are forced over the opposite edge of the rail base.

In applying the anchor to a rail, the jaws 23, 24, are hooked over one edge of the rail base. substantially as shown in dotted lines in Fig. 2. The end 12 of the anchor is then forced upwardly toforce the cam surfaces 19b and the jaws 19, 19aL over the rail base. rlhe pressure of the cam surfaces 19b against the edge ofthe rail moves the arms 13, 14, bodily transversely of the rail, and flexes the angularly disposed ends 21, 22 from the dotted line position of Fig. 1 to the full line position. As soon as the jaws 19, 19'Ll clear the upper edge 18 of the rail base, the resiliency of the metal from which the device is formed causes the said jaws 19, 19l to snap over the upper edge of the rail base. After the jaws 19, 19a snap into position, the jaws at the opposite edge ofthe rail may be driven into wedging engagement with the rail. base. The resiliency or the metal exerts a strong spring grip upon the rail. which in itself will, ordinarily be sufficient to resist the creeping movement of the rail. Any creep- The lower jaws are made someing movement ol' the rail, however, will tend to move the jaw 19 toward Vthe cross tie 26 and thereby subject the yoke to increased tension.

ifhile l have described my invention in connection with one speeiic` enibodiinentLit will rbe obvious that modifications might be made without departure from theV spirit of niy invention. l therefore wish it understood that l contemplate all such changes in construction come `within the scope ot the appended cla` ins.
